Learning about how much our pious predecessors would cry whenever they missed out on a chance to perform virtuous deeds. The Prophet said: “The people of Paradise do not regret anything more than regretting an hour they spent (in this life) without mentioning Allaah.” [At-Tabaraani].Sa’eed At-Tanookhi used to cry if for any reason he had missed a congregational prayer. Ibn Mas’ood, said, “I never regretted anything more than regretting a day which passed in which I did not increase (upon) my virtuous deeds.”
